Why am I receiving a lot more than last year?

[AmyW · Accepted solution]

If your total tax payments and credits are greater than your total tax liabilities, then you will receive a refund for the overpayment. If you received refundable credits, your refund may be greater than the amount of tax paid Just in case, you should review your return, checking your date entries starting with your W-2, looking for errors such as misplaced decimals or extra zeros. 

Please note that many state forms haven't yet been finalized by the states. Until the forms are finalized, the calculations may not be correct.
